Abstract
Mold for producing, or casting, a high-melting metal article from a high-melting metal having a melting point of about 900 to 1600 DEG C and a method of producing a high-melting metal article by using the mold (A). The mold comprises a pair of male (a1) and female (a2) molds provided with a core (5, 5') part or liner (2) part, one or both of the male and female molds formed of a ceramic, a vent provided by incorporating a heat-resistant, porous, gas-permeable material into the core part or liner part, an auxiliary vent (8a) leading from a predetermined part of mold cavity surfaces to the exterior of the mold, a well (8b) provided in the auxiliary vent in the vicinity of the mold cavity (b) surface, and a vent plug (9) provided at the outlet of the auxiliary vent so as to be capable of being freely inserted and drawn out, the vent plug formed of a ceramic (7a) or a heat-resistant, porous, gas-permeable material. According to the method, gases generated in the solidification process of the molten metal are sucked out through the vent formed in the core part or liner part, and the vent plug is drawn outward by a minute amount at a predetermined timing from the start of the pressurization of the interior of the mold cavity so that internal gases generated at a predetermined part of the interior of the mold cavity (at a thicker part where solidification occurs later than at other parts) are effectively discharged into the well in the auxiliary vent by the time the molten metal at the predetermined part is solidified, whereby even an article having a thicker part is molded without leaving gases in the thicker part.
